A display panel and a display device are provided. By configuring an auxiliary cathode layer such that a lateral end of a second auxiliary cathode extends beyond a lateral end of the first auxiliary cathode, a full-surface application of light-emitting materials can be realized during the formation of subpixels. This setup facilitates the segmentation of the light-emitting material layer, enabling the formation of light-emitting material sections in the respective subpixels, with cathodes aligned with the light-emitting material sections. This design prevents overlapping of different light-emitting colors that could lead to display anomalies. Accordingly, the display panel operates effectively without the need of using mask plates for forming the subpixels, increasing the pixel density of the display panel. Also, the contact between the cathode and a lateral side of the second auxiliary cathode reduces the impedance of the cathode.

Abrégé

The present invention relates to a display panel and its manufacturing method. The invention uses a lanthanide series element and scandium co-doped indium zinc oxide to prepare an oxide as the first active layer of the GOA region. The lanthanide series element suppresses the formation of excessive oxygen vacancies and serves as a conversion medium under blue light with low charge transfer transition energy. This greatly improves the stability of the thin-film transistor in the first active layer of the GOA region without affecting mobility. Scandium helps to suppress the formation of excessive oxygen vacancies, control carrier concentration, and maintain lattice matching, further enhancing the stability of the thin-film transistor in the GOA region.

A display panel and a display device. The display panel includes a first display area and a second display area, a light transmittance of the first display area being greater than that of the second display area. The first display area is provided with first light-emitting devices and second light-emitting devices, which are arranged adjacent to each other. By making the light transmittance of the first cathode of the first light-emitting devices less than that of the second cathode of the second light-emitting devices, the difference in reflectivity between adjacent light-emitting devices is increased. This reduces the intensity concentration in the direction of diffraction of the first display area and disrupts the array diffraction between adjacent first and second light-emitting devices.

A display panel, a manufacturing method of the display panel, and a display device are provided. The display panel includes a display area and a non-display area. The non-display area surrounds the display area. The display panel further includes: a substrate; a first thin film transistor (TFT) disposed in the non-display area, where the first TFT includes a first drain layer placed on one side of the substrate; a second TFT arranged in the display area, where the second TFT includes a second gate layer placed on one side of the substrate. The first drain layer and the second gate layer are arranged in a same layer. By forming the second gate layer and the first drain layer in a same process, the number of photomask processes can be reduced compared to the conventional display panel. This reduces the number of steps.

A spliced display screen and a spliced display device are provided. The spliced display screen includes gate driving units arranged within pixel units to drive these pixel units, eliminating the need for binding scan chips. This approach can reduce the number of side wirings and binding terminals, thereby improving the yield of the spliced display screen. Additionally, by placing both scan terminals and data terminals on the same side of the display area, the display panel is designed with connecting terminals on only one side, effectively eliminating a border on one side of a display panel. Moreover, a terminal area of one display panel is arranged corresponding to the display area of another display panel, and therefore, a splicing seam is minimized or even eliminated.

Abrégé

A display panel and manufacturing method thereof are provided. The display panel includes a first display area and a second display area surrounding the first display area. The display panel includes: a first substrate, including base islands; light-emitting elements arranged on the first substrate; and a second substrate set on the light-emitting elements. The second substrate includes grooves arranged in the first display area. These grooves can increase the elasticity and stretchability of the second substrate in the first display area, making a stretch film in this area more easily stretchable and deformable, reducing stress concentration. This design aims to prevent excessive force and deformation in a middle part when the display panel is stretched upwards, thus minimizing stress concentration in this area. By allowing a smoother stretch in the first display area, it prevents issues of uneven display effects and abnormal screen problems.
